Up to date, Sticky Add To Cart bar shows variant picker and change option, even if there is only one variant of the product. Logically, the “change” option should disappear when there is only one product variant. Otherwise it is confusing for the customer, with the Change link that goes nowhere. I strongly believe everything that is about adding to cart should be very straightforward and clear to the customer.
Thank you for considering.
